Needless to say, in future sessions we did shit like ordered pizza, but he would also scarf down half the pizza before everybody else had finished their first piece. Gluttonous asshole. (He wasn't even that fat, somehow)
-At a certain point, he just stopped rolling dice for stuff altogether, arbitrary deciding when we got hit or didn't. Occasionally he would have us call high or low, or even or odd or some shit for things like fucking saves. (Instead of rolling a will save to resist being mind controlled for example, he would just have us call even or odd or high or low or some shit, when he was feeling generous and actually let us participate.)
And you might think, "well, maybe he just really wanted to tell a story."
Fucking wrong. His DM style could basically be called "stream of thought DMing," basically throwing us into whatever situation came to mind, in an extremely disjointed manner. One time we went from being in the deepest shithole in the underdark, to being on a pirate ship on the ocean. From a port. In the underdark. To the very above-ground ocean. And then it turns out his rogue DM PC knows the captain, who just happens to be here, in an ocean port in the underdark, after we had essentially been wandering aimlessly for days.
We literally went from traveling a normal road; to investigating a necromancer's keep; to literally falling into the underdark; to some strange demi-plane of some god he probably made up on the spot, where he basically said "look at all this cool stuff, oh shit you are being chased, run away!"; to stumbling back into the underdark, physically, like, there was a door; to the aforementioned pirate ship. All in one session that took about four hours maybe.
The spell list was just not a thing he consulted. His idea of a spell was "what do I want to have happen to that person? Okay, that is a spell now"
